Last min. AC reccomendations before I pull the trigger

72 K10 suburban with factory front and rear AC.
Swapped in a 5.3 4L80e combo and have a sanden type compressor ready to go.

When I bought it the previous owner said he had the system recharged 2-3 times and it worked for about a week then didn't so it has a obvious leak but he didn't know from where.

I kind of hate all the bulky mess of the original AC setup so I planned to get a vintage air/classic air, etc...

Reading through years of threads Vintage Air genIV surefit seems to be the best performing however only for the front driver/pass. Some people reccomend getting the slimline for the rear whereas other people have said that VA also makes a monster cooler but it's not a sure fit system.

Any reccomendations before I pull the trigger?

I haven't had the stock rear AC tested so I don't know if the leak is there. The fan does work and it has the lines all hooked up.

Re: Last min. AC reccomendations before I pull the trigger

I have no experience with the aftermarket units.

I think running both the front and rear units that the displacement of the compressor will be important. As well as the size of condensor. It might be worth a call to vintage or classic for their recommendation.

The sanden compressors are popular but come in different displacements depending on system sizes.

The rear evaporator core and expansion valve are still available new on rockauto if you are concerned.

Are you replacing hoses too? I installed barrier hoses on my Suburban because I am going to use R134a refrigerant.
